So, I received my brand spanking new fuel injection pump. It's so shiny and new with that new pump smell, I almost hate to use it! It may well be the last one in stock anywhere. Came direct from Yanmar and their inventory only showed 1 left.....could be a collectors item! Interesting thing to note, the **** thing came with the fuel line connectors that you can no longer find anywhere from Deere, so I'm wondering if Yanmar has those available as OEM parts somewhere in their catalog. My old ones had been cross threaded a few times and I was able to clean up the threads pretty well with a tap & die, but now that I have new ones, yahoo!
So, I've read through the tech manual a few times and I think I've got this (he says silently wishing he had a close friend that was a mechanic). But it's the timing that worry's me. I attempted to check the timing on the existing pump but it didn't seem to do what was expected per the tech manual. I'm chalking that up to the pump being bad and hope to have a different experience after I install the new pump. Now that I have taken off the radiator, that will be easier too.
So, a few questions.
1.) I made a "timing tool" out of my old fuel line that I'm replacing. However, upon reading the tech manual again today, I discovered that is says to make it out of a different fuel line from another model (which of course is not available). I had assumed it was talking about a fuel line from this tractor (ya ya, never ***-u-me). Will this make any difference? Would the i.d. be different or anything that would make mine not work right? I barely understand how this timing is supposed to work, so I'm checking the details. Tech Manual excerpt below.
2.) Thinking back to my youth as a go-fer named "goddammit", I vaguely remember a trick to making the timing mark more visible/clear on the wheel. I'm thinking it was to put nail polish on it (but that was the solution to a lot of things back then). The timing marks on mine are barely visible and have been painted over, so I was going to clean them up and then do something to enhance the embossed mark. Suggestions welcomed. Thinking permanent marker might do well too.
3.) Tips, tricks, hints are greatly appreciated on checking the timing. I get the point to use the same number/size of shims that are under the current pump, but I'm guessing I'll have to re-time this because its a brand new pump.
4.) I've cleaned up the area around the pump pretty well (good ole simple green!), but I'm curious why that's stressed so much. doesn't the pump sit in the crank case? a little dirt wouldn't be good (never is), but would be picked up by the oil filter, right? Just looking to see if I need to be surgical/clean room about this or just reasonable.
I'm off to do mundane things and wait anxiously for good weather this weekend to git 'er done.
As always, thank you for the advice.
